Definitions

  • the winning machine accordinging to the instant invention is adaptable to both low-speed and high-speed operation as well, since it accomplishes its function of winning reaction compensation by controlling the relative peripheral speed of its counter-rotating cutter heads, and not by mere counter-rotation of the cutter heads alone, as in prior art winning machines.
  • the net force and moment exerted on the entire machine can be adjusted so as to cause it to advance in a selected direction, precisely guided under the influence of said net force and moment.
  • Control of the peripheral speeds of the individual cutter heads in the winning machines is achieved by driving them through a gear drive mechanism having one output drive shaft connected to each cutter head, and gear shifting means for varying the transmission ratio between each out-put shaft and a single input drive shaft which is connected to a rotary prime mover.
  • the peripheral speeds of the rotary cutter heads, and hence the net force and moment acting on the Winning machine are controlled by individual variable speed drives connected to each cutter head via gearing.
  • This particular embodiment lends itself readily to conventional automatic control devices for establishing the peripheral cutter speeds required for a given direction of advancement.
  • control and utilization of the aforesaid winning reaction effects can also be achieved by varying the relative spatial and angular disposition of the cutter head axes of rotation.
  • Another and further object of the invention is to provide a winning machine as aforesaid, wherein the controlled reaction forces can be utilized for the precise and reliable guidance of the machine in a selected direction of advancement.
  • Still another and further object of the invention is to provide a winning machine as aforesaid, which is adaptable for both low-speed and high-speed operation.
  • FIG. 1 is a longitudinal view, partly in section, of a winning machine, according to another embodiment of the invention, shown apart from its associated machine frame;
  • FIG. 2 is a longitudinal view, partly in section, of a winning machine, according to another embodiment of the invention, also shown apart from its associated machine frame.
  • a winning machine W is provided with a pair of concentrically disposed cutter heads 1 and 3 which are fastened to the shafts 2 and 4 respectively, and are rotatably supported by a machine frame (not shown) via the outer bearings 5 and inner bearings 6.
  • the shaft 2 is disposed within the hollow shaft 4 and is guided therein by the bearings 6.
  • the hollow shaft 4 is guided in the bearings 5 which are supported by the machine frame (not shown), so that the shafts 2 and 4 have a substantially common axis of rotation, fixed in relation to the machine frame and the gear drive mechanism 20.
  • a gear 21 affixed to the shaft 2, and an integrally formed gear 22 disposed externally on the shaft 4 are provided for rotatable driving the cutter heads 1 and 3 respectively.
  • the gear drive mechanism 20 shafts 23, 24 and 25, any one an input shaft.
  • any one an input shaft For simplicity, sidered as the input shaft.
  • the though rotatable, are supported fixedly in relation to each other and to the machine frame (not shown).
  • the input shaft 24 is operatively connected to be rotated by a prime mover (not shown) and is provided with three of which can be used as the shaft 24 shall be conshafts 23, 24 and 25, al-
  • the gear drive mechanism is shown in one particular gearing configuration (i.e., gears 7, 8 and 9 in mesh).
  • gears 7, 8 and 9 in mesh
  • another set of transmission ratios is provided by the gears 10, 11 and 12, which are also aflixed to the shafts 23, 24 and 15 respectively.
  • Either of these two sets of transmission ratios can be selected as desired or required to establish a particular winning reaction condition by means of the gear shifter 14, which is operated by conventional means (not shown). If desired additional gears (not shown) can be provided on the shafts 23, 24 and 25 to increase the number of transmission ratio sets which are available.
  • an idler gear 26 is interposed in the power transmission path from shaft 23 to shaft 2, as between the gear 15 afiixed to shaft 23 and gear 21, with the shaft 4 being driven directly by shaft 25 via gear 27 affixed thereto and gear 22.
  • the idler gear 26 can be interposed between gears 22 and 27, (i.e., in the power transmission path from shaft 25 to shaft 4), instead of between gears 15 and 21 as shown.
  • T T and T are the torques transmitted in the cutter heads 1 and 3 and in the shaft 24 respectively
  • W1, W3 and W24 are the respective angular velocities of said cutter heads 1, 3 and shaft 24.
  • reaction forces and moments will be imposed on the cutter heads 1 and 3 at those cutters 28 which engage the mineral deposit.
  • the direction of the reaction forces will vary with the portions of the cutter heads 1 and 3 having cutters 28 in mineral-winning engagement.
  • these reaction forces and their moments can be utilized to guide the winning machine W in a desired direction.
  • Such guidance can be obtained by an operator (not shown) observing the progress of the mineral-winning machine and manipulating the gear shifter 14 and prime mover (not shown) output so as to cause the cutter heads 1 and 3 to progress in a desired direction.
  • such guidance can be obtained automatically through the use of a conventional control system (not shown) in lieu of an operator.
  • the gear drive mechanism 20 is substantially replaced by independent drives 13 which can each include a prime mover such as a motor, or be operatively connected to be driven by individual prime movers.
  • the drives 13 are variable speed drives such as, for example, a DC. motor, or a combined motor and variable speed transmission, so that the cutter heads 1 and 3 can be operated at such speeds as are required for the purposes of the invention.
  • variable speed drives 13 are each capable of covering a continuous speed range, such as, for example, where the drives 13 include DC. motors.
  • the winning machine of the instant invention is not necessarily limited to the use of two concentric counter-rotating cutter heads, as illustrated by way of example in FIGS. 1 and 2, but may be provided with additional cutter heads which can either be mounted concentrically, or in spaced relation to each other, or even with their rotation axes angularly inclined with respect to each other.
  • a winning machine comprising a machine frame, a pair of concentrically rotatable cutter heads supported by said machine frame, a variable transmission ratio gear drive having an input shaft connectable to a prime mover for rotation thereby, a pair of output shafts each connected to a corresponding cutter head to transmit rotary power thereto from said input shaft to counterrotate said cutter heads, and gear ratio change means operable to vary the rotation speeds of said cutter heads to maintain a selected rotary speed ratio between said cutter heads to correspondingly regulate the net reaction force and moment transmitted to the machine frame through said cutter heads.
  • said gear ratio change means includes a plurality of selectively intermeshable gear sets, each gear set including three gears, one mounted on said input shaft and one mounted on each output shaft, each gear set corresponding to a characteristic cutter head speed ratio.
